DOE on track to deliver high-burnup SNF to Idaho by 2027
The Department of Energy said it anticipated delivering a research cask of high-burnup spent nuclear fuel from Dominion Energy’s North Anna nuclear power plant in Virginia to Idaho National Laboratory by fall 2027. The planned shipment is part of the High Burnup Dry Storage Research Project being conducted by the DOE with the Electric Power Research Institute.
As preparations continue, the DOE said it is working closely with federal agencies as well as tribal and state governments along potential transportation routes to ensure safety, transparency, and readiness every step of the way.
Watch the DOE’s latest video outlining the project here.

Ion heating experiments have been intensively carried out in high- and low-Zeff conditions of Large Helical Device plasmas. In high-Zeff plasmas utilizing neon or argon gus puffing, the ion heating power normalized by ion density (Pi /ni) increases with ZeffL and the central ion temperature increases with Pi /ni without saturation. The central ion temperature of 13.5 kV was achieved in an argon-seeded plasma, strongly suggesting the capability of the helical configuration to confine high-performance plasmas. In low-Zeff experiments, improvement of ion heat transport was realized in the core plasmas heated by high-power neutral beam injections. The ion temperature has a peaked profile with steep gradient in the core region (ion internal transport barrier). The transport analysis indicates that the anomalous transport is reduced in the core region, where the negative radial electric field is predicted by the neoclassical ambipolarity. Improvement of ion heat transport with positive radial electric field was also successfully demonstrated utilizing strongly focused electron cyclotron resonant heating, suggesting further improvement of ion heat transport in reactor-relevant plasmas.
